Abstract: This study examines the influence of sustainability leadership and schoolcommunity partnerships on organizational sustainability. This study also examines the influence of human resource competency on school-community Data collection in this study used a survey with a questionnaire. The determination of the sample for this study follows the opinion of Mwenda et al. , namely managing the target population using a census approach which means that all existing work units are research samples. This study is a study at the work unit level, so the sample determination uses a census approach, namely if the population is less than 200 units, all work units are samples (Israel. The research sample consisted of 20 work units of vice principals from five schools based on certain religions in Java. Hypothesis testing in this study used partial least squares structural equality modeling (PLS-SEM). The findings of this study are that there is a significant relationship between sustainability leadership and school-community partnerships with organizational sustainability and the influence of human resource competency on schoolcommunity partnerships. The practical implications of this research for principals and school administrators are that sustainability leadership and school-community partnerships build organizational sustainability and human resource competency builds school-community partnerships. In future research, the same thing can be studied in terms of indirect relationships, either through mediators or mediation. Keywords: Sustainability Leadership. Organizational Sustainability.

Accepted: 2025-09-29 Introduction An organization is a system consisting of several people and has activities to achieve goals (Bittner, 1965 . Gutterman, 2. An organization can be formed because of the same vision and mission and the same goals of its members (Gutterman, 2. In its development, many organizations are stagnant or running in place (Musakki, 2. This is caused by . a vision and mission that is not implementable, . doing what is there, . the organizational philosophy is not continuous, and . lack of monitoring and evaluation (Musakki, 2. Ideally, the organization continues to achieve its goals (Gutterman, 2. Schools are one of the organizations that also have the threat of stagnation so that they are eventually closed or merged International Journal of Economics.

The main phenomenon of schools not being able to survive sustainably due to a lack of new students (Saputra, 2016. Pitonang, 2016. Pitonang, 2024 ) and costs are seen as burdensome by parents (Yulia Nurhalisa, 2. Ideally, schools provide a variety of inclusive, equitable, and quality learning opportunities (Brandisauskiene et al. , 2. and continue to survive or be sustainable (Gutterman, 2. Another phenomenon is the existence of different policies, specifically for public schools, two conflicting policies were found. First, the education office policy to close schools (Saputra, 2. because the number of students does not match the quota. Second, to maintain the existence of schools even though the number of new students is insufficient (Sugiarti, 2. The policy of not closing schools is closely related to the vision and mission of the relevant agencies that want to improve the quality of education, realize that schools will always be needed, and continue to provide school access to communities in remote areas because some schools with minimal students are in remote areas (Sugiarti, 2. This is support for the sustainability of schools which is an important thing that should be fought for. School organizational sustainability is very important because school services have an impact on students' attitudes, values, and behaviors (Admin Future Teacher, 2. , provide wider learning opportunities and strengthen communities (Admin We Forum, 2. , address inequalities and teach universal values (Sewchurran, 2. In addition, schools can build the future as a place to achieve social and sustainable goals, diversity, and well-being (StanevaBritton, 2. There are several factors in achieving school organizational sustainability, such as leadership (Wiratnadi et al. , 2. , school and community partnerships (Ngobeni, 2. , and human resource competencies (Sarjana. et al. , 2. Sustainability leadership for organizations is a must because sustainable leadership is the type of leadership that is appropriate for organizational sustainability (Cheah & Ooi, 2. Leaders continue to practice sustainability leadership to achieve goals in a rapidly changing environment (Hurst, 2. and initiate and implement organizational sustainability goals (Boeske, 2. The influence of sustainability leadership on organizational sustainability is still relevant to be studied as well as to fill the research gap as suggested by Cheah & Ooi . that further research is still needed to establish the role of dynamic and globally impactful sustainable leadership on organizational sustainability. Also according to Zen's suggestion . that research on sustainability leadership on organizational sustainability can also be continued with other variables. Schools are an integral part of the community and it is very important for schools to collaborate with the private community through collaborative programs (Ngobeni, 2. Schools have an environment and do not stand alone without the community, and schools are never the only source of education (Benson et al. , 2. According to Lasker & Weiss, through school-community partnerships, schools can do more services (Ngobeni, 2. and help schools engage with the wider community and develop meaningful and sustainable relationships (DePetris & Eames, 2. A large number of studies on school-community partnerships have been conducted but there is still an opportunity to examine the role of schoolcommunity partnerships on organizational sustainability (Ngobeni, 2. Human resource competency is one of the important elements in shaping the development of an organization (Tataw, 2. and to drive organizational performance in creating sustainable competitive advantage (Mohd Salleh et al. , 2. Human resource competency is a set of behavioral patterns that include knowledge, skills, and attitudes in carrying out their duties and functions (Mohd Salleh et al. , 2.

Based on this, this study focuses on the influence of sustainability leadership on organizational sustainability. This is new in this study. For this reason, in terms of previous research and the novelty and situation of the schools that are the subjects of the study, this study aims to produce an analysis of sustainability leadership and school-community partnerships and human resource competencies that can support organizational sustainability. Organizational sustainability guarantees the implementation of services and actualizes the school's vision and mission, so organizational sustainability becomes very important. Literature Review Sustainable leadership is a type of leadership that is appropriate for organizational sustainability because sustainable leadership positions goal achievement as the main thing for a sustainable future (Cheah & Ooi, 2. Furthermore, according to Cheah & Ooi . , sustainable leadership for organizations is a must for organizational sustainability. This is as stated by Hurst . that managers or leaders continue to practice sustainable leadership to achieve goals in a rapidly changing environment. Leadership facilitates the initiation and implementation of goals for organizational sustainability (Boeske, 2. Sustainable leadership is a leadership model in a leader who drives the sustainability agenda in the organization (Hira, 2023. Muliyah et al. , 2. , leaders have a deep understanding of the impact of the organization on the environment, society, economy, and strive to create harmony between organizational interests, environmental sustainability, social welfare, and long-term economic sustainability (Muliyah et al. , 2. Sustainability is conceptual (Elkins et al. , 1. and very popular (Salzmann et al. , 2. However. Olawumi & Chan . stated that there is no agreed definition of sustainability because sustainability is often misunderstood as sustainable development. Organizational sustainability is the ability of an organization to deal with issues during a crisis with assumptions, attitudes, and beliefs so that the organization continues to be able to operate to achieve goals with sustainable development methods to ensure the survival of the organization (Rahman et al. , 2. According to Kidd . , organizational sustainability is shaped through a number of political, public, and academic influences over time (Linnenluecke & Griffiths, 2. Organizational sustainability focuses on environmental, social, and economic Sustainability is a prerequisite for an organization to survive (Varsei et al. , 2. its focus, sustainability consists of three core pillars, namely social, environmental and economic sustainability, all of which must be balanced to achieve sustainable development International Journal of Economics.

In line with the focus and pillars of organizational sustainability, according to Bom et al. , organizational sustainability has three dimensions, namely environmental, social and economic sustainability dimensions. Environmental sustainability is the competence of an organization or organizational performance to reduce carbon footprints (Lam & Lai, 2. which has implications for four main natural resources, namely air, water, land, minerals and energy resources (Global Reporting Initiative (GRI), 2. Social sustainability is the organization's ability to address internal and external human resource issues that include job security, accommodation, health and safety, and capacity development (Ahmadi et al. , 2. Economic sustainability is the ability of an organization to maintain the economic conditions of stakeholders and the economic system at the global level. national and global that can survive in the long term (Svensson, 2. Sustainable leadership is a type of leadership that is appropriate for organizational sustainability because sustainable leadership positions goal achievement as the main priority for a sustainable future (Cheah & Ooi, 2. First of all, sustainable leadership was developed by Hargreaves & Fink . based on educational organizations (Liao, 2. In terms of its characteristics, sustainable leadership refers to the values of sustainable development and sustainable awareness held by leaders which are manifested in their work. Sustainable leaders are more likely to adopt a responsible attitude towards sustainable initiatives and activities. this basis, leaders will create a sustainable organizational environment, build sustainable organizational goals and play a responsible role in protecting the ecological environment (Liao. According to Hargreaves & Fink . sustainable leadership has six dimensions, namely . encouraging continuous learning, . creating internship leaders in schools, . building a culture of sharing and learning among teachers, . encouraging partnerships with peers and organizations outside the school, . diversity, and . What is meant by encouraging continuous learning is seeing leadership as a quality culture that is integrated with a holistic approach to sustainable leadership, while creating internship leaders in schools is an effort by leaders to carry out leadership regeneration by providing the knowledge and skills needed to facilitate the implementation of change, improvement, and the impact of change. for building a culture of sharing and learning, it is an effort to build a leadership culture that is spread throughout the organization by delegating tasks. The dimension of encouraging partnerships with peers and organizations outside the school means that schools collaborate with other parties for school sustainability. The diversity dimension is a view, idea, and creativity that is suggested for members of the organization with staff development to become more independent and creative and sustainability is a dimension that focuses on the sustainability and long-term success of the organization (Hargreaves & Fink, 2. School-community partnerships are an effort to improve the well-being and life prospects of students, strengthen families, and even transform integrated and comprehensive communities (Valli et al. , 2. School-community partnerships can also mean a way of working that implements collaborative relationships between entities that are carried out by working together towards common goals through mutual agreement. School-community partnerships can provide broader learning opportunities in schools, provide services, and comprehensive support for students who need them (Olson, 2. The dimensions of schoolcommunity partnerships consist of seven dimensions (Parent Victoria, 2. First, communication, which is how schools and parents or other parties build relationships by increasing community involvement in schools. Second, learning relationships at home and school, which means that schools, parents, and communities value the learning environment at International Journal of Economics.

Third, building communication and identity, namely schools with friendliness and openness support and develop students' identities, competencies, and sense of belonging. Fourth, recognizing the role of the family is all elements, both schools and families, respect each other's roles to complement students' education. Fifth, consultation in decision-making is the school has openness resulting in shared responsibility and Sixth, collaboration which means community involvement enriches learning, student welfare, and school resources. Seventh, participation which means families or communities contribute through school activities both through learning and other activities. Human resource management plays a vital role in organizational excellence (Ribeiro & Gavronski, 2021. Rowshan et al. , 2. The complexity of managing these resources sustainably requires managers to have technical knowledge and the ability to demonstrate a level of adaptability (Olsen et al. , 2. Therefore, competence is essential for building longterm competitive advantage. Competence is a characteristic . ndividuals that enable them to carry out entrusted tasks (Matwiejczuk, 2. effectively, which includes knowledge, skills, and abilities (Ribeiro & Gavronski, 2. According to Brockbank et al. , human resource competence has six dimensions. First, personal credibility is an individual living according to organizational values, based on trust and acting with an "attitude" of how the organization can achieve its goals. Second, the ability to manage change which means the individual's ability to examine problems, build relationships with clients, articulate a vision, set a leadership agenda, solve problems, and implement goals. Third, the ability to manage culture is a dimension related to the individual's ability to identify the culture needed to meet the needs of the organization's strategy, frame the culture to inspire employees, translate the appropriate culture into organizational behavior, encourage leaders to behave consistently with the established culture. Fourth, the delivery of human resource practices is a dimension related to the ability to innovate in areas such as recruitment, employee development, compensation and communication. The fifth is the business understanding dimension which is dimensions related to an individual's ability to understand strategy, organization, competitors, finance, marketing, marketing team management, and information technology (Brockbank et al. , 1. The implementation of sustainability leadership in the organization through leaders and members of the organization encourages the growth of school-community partnerships and human resource competencies. From the entire organizational process, sustainability leadership determines the success of organizational sustainability, sustainability leadership drives schoolcommunity partnerships, and encourages increased competency of human resources working in the organization and ultimately builds organizational sustainability. Research Methods This study uses a quantitative method approach, which means that researchers formulate problems and then identify them into hypotheses. The population of this study refers to all groups of people, events, or interesting things that researchers want to investigate (Sekaran & Bougie, 2. , namely vice principals. The determination of the sample for this study follows the opinion of Mwenda et al. , namely managing the target population using a census approach, which means that all existing work units are included in the research sample. This study is a study at the work unit level, so the sample determination uses a census approach, namely if the population is less than 200 units, all work units are samples (Israel, 1. Thus, the number of samples for this study is 20 work units in the school, namely four work units of vice principals. International Journal of Economics.

The selected high schools were high schools that had four vice principal work units led by a vice principal and each vice principal had a team and high schools that had a minimum of 250 students. The five schools had four vice principal units or fields, namely the vice principal for curriculum, vice principal for student affairs, vice principal for public relations, and vice principal for facilities and Thus, each school consisted of four work units, so the population of this study was 4 work units x 5 schools = 20 work units. Each work unit was represented by two of the vice principals who were the core administrators of each field/unit so that the number of respondents included 2 x 20 work units = 40 respondents. For the data on 20 work units, it was obtained from the answers of two representatives from each work unit which were added and then divided by two. The result of the division was the data on the vice principal work units. The determination of respondents was carried out by asking for assistance from the principal so that the principal selects respondents from each work unit of the vice principal in his/her school who meet the criteria, namely . permanent employees, . have worked at the school in question for at least six months, and . have been the vice principal or vice principal team for at least six months, and . represent the work unit of the vice principal in preparing the work program and budget. A questionnaire survey was conducted to collect data from 20 work units of vice principals. A questionnaire with a five-point Likert scale was used to measure the respondents' The Likert scale measures how much respondents agree or disagree with a given statement (Sekaran & Bougie, 2. The scores given are strongly disagree . , disagree . , neutral . , agree . , and strongly agree . The sustainability leadership instrument was adopted from (Howa & Ishakb, 2. , human resource competencies from Ulrich et al. , school-community partnerships were adapted from Parent Victoria . , and organizational sustainability from Hristov & Chirico .

As seen from Table 3, all variables in this study have good discriminant validity. After the data is declared valid and reliable, data analysis can be continued to the second stage, namely identifying the goodness of fit of the research model and testing the hypothesis. Identification of goodness of fit is a test or assessment of a structural model based on bootstrapping and blindfolding. To assess the structural model focuses on evaluating the significance and relevance of the path coefficient, the size of R2 . ariance explanatio. Q2 . redictive relevanc. , and f2 . ffect siz. (Hair et al. , 2. Multicollinearity is a statistical phenomenon that is often encountered with the presence of two or more independent variables in a highly correlated multiple regression model (Sekaran & Bougie, 2. Structural models that use reflective indicators do not actually have to measure multicollinearity (Hair et al. This study still tests for multicollinearity to ensure that multicollinearity does not occur. The measurement used is the variance inflation factor (VIF). Common VIF parameter values are those that correspond to VIF O 10 (Sekaran & Bougie, 2. Based on Table 4 below, the inner VIF results for all variables are <10, so there is no multicollinearity.

OS has antecedents or independent variables SL and SCP, . HRC has antecedents SL, . SCP has antecedents HRC. The next discussion is a discussion of the interpretation results and a discussion of the findings of testing each hypothesis. The effect of SL on OS shows that H1 is accepted. The path coefficient H1 shows a positive This result means that the better the SL, the better the OS. This finding answers the first objective of this study, which is to test SL against OS in the work units of vice principals in The results obtained can be interpreted that SL has a direct, significant and positive influence on OS in the work units of vice principals. In previous studies, it was found that the results of research on the influence of SL in the world of education were found to be research on sustainable leadership practices and their dimensions among female secondary school leaders from the perspective of female teachers (Murtadaz & Al-Zar'ah, 2. , sustainable leadership practices in schools from the perspective of teachers (Elkaleh et al. , 2. , and the impact of sustainable leadership on the quality of education (Peng et al. , 2.

On the one hand. Zen . clearly suggests that research on sustainable leadership on organizational sustainability can also be continued with other variables. Based on the previous research above, there is still a wide gap of novelty for this research which examines the influence of sustainability leadership on organizational sustainability in terms of the vice principal's work unit in schools. Research on the influence of sustainability leadership on organizational sustainability in terms of the vice principal's work unit without considering the gender of the respondent has not been found so this is a novelty of this research.

The effect of HRC on SCP shows that H2 is significantly accepted and has a positive path coefficient value. These results indicate that the better the HRC, the better the SCP or if HRC increases well. SCP also increases well. These results answer the second research objective, which is to test HRC against SCP. The interpretation of the results of this study is that HRC has a significant and positive direct effect on SCP. It is very difficult to find previous research on the effect of HRC on SCP. Several previous studies are related to human resources that have an important role for the organization (Aris et al. , 2. , human resources and teacher effectiveness (Muhammad & Satatu, 2. , implementation of competency-based human resource development practices among educators (Hantoro et al. , 2. Human resource competence is one of the important elements in shaping the development of an organization (Tataw, 2. is also very effective in driving organizational performance and creating sustainable competitive advantage (Mohd Salleh et al. , 2. Related to human resource competency, there are two suggestions found. The first suggestion was conveyed by PurgaC-Popiela . that research is still needed on the unique characteristics of organizations . n small and medium enterprise. in order to understand how human resource competency practices affect sustainability. Second, the suggestion of Setya Bangsawan & Kurniawan . who suggested that research on the influence of human resource competency related to other variables with research subjects outside the tax office still needs to be studied. Based on these suggestions, this study places HRC and SCP on whether they affect OS in the world of education, namely high schools. HRC has a significant and positive direct influence on SCP. The influence of HRC on SPC is at a moderate level, namely 527 as can be seen in Table 6. Schools realize the importance of human resource competency, which means that schools with school resource competency have an understanding that achieving goals is the main thing for a sustainable future and as an effort to sustain the organization with the ability to build SCP. Good HRC will have an impact on SCP getting Previous research related to HRC found that increasing HRC to improve the performance of MSMEs human resource competencies to improve the performance of Micro. Small, and Medium Enterprises (Widyanty et al. , 2. and HRC can affect employee performance (Indiyati et al. , 2. On the one hand. HRC is one of the strategies to improve skilled communication and service so that it can develop work networks (Manteiro et al. , 2. The results of this study can support the research of Manteiro et al. which in this study places the HRC variable. Schools have an understanding that HRC is very important for International Journal of Economics. Business and Accounting Research (IJEBAR) Page 725 International Journal of Economics.

Issue-3, 2025 (IJEBAR) E-ISSN: 2614-1280 P-ISSN 2622-4771 https://jurnal. stie-aas. id/index. php/IJEBAR building SCP. HRC can encourage human resources to build networks (Manteiro et al. , 2. With the ability of human resources to build networks, schools have the resources to build a movement on how to involve parents and the community to help schools so that school goals are achieved (County, 2. When human resources have the ability to build networks, the atmosphere of social ties in schools can be developed to be stronger which has an impact on the development of the educational process as a collective effort ( Mu'ammaroh et al. , 2024 ) . In principle, with HRC. SCP can be built so that schools have important support in achieving school success. SCP plays an important role in schools (County, 2005. Gross et al. , 2015. Mu'ammaroh et , 2. Related to the influence of SCP on OS, it shows that H3 is significantly accepted and has a path coefficient value with a positive direction. These results indicate that SCP has a positive effect on OS so that when SCP increases. OS also increases. The results of this study answer the third research objective, namely to test SCP on OS. The results of this study can also be interpreted that SCP has a significant direct effect on OS. The influence of SCP on OS is high, approaching 0. 7, which is exactly 0. Previous studies found that SCP data build sustainable planning (Exmeyer et al. , 2. SCP can be applied in government, universities, schools, companies, and non-profit organizations (Tranel, 2. On the one hand. SCP can be a new challenge but can still help in decision making specifically in risk mitigation (Sun et , 2. and SCP can also be useful for solving social problems that occur in communities or schools (Clarke, 2. Based on previous research, it is still very open to research the influence of SCP on OS in terms of the vice principal's work unit in schools. This research on the influence of SCP on OS in terms of the vice principal's work unit is focused on previous studies that focus on global issues in institutions. This study found that SCP is an important factor for OS with a strong influence, namely 0. Schools are aware that SCP is very important to achieve organizational sustainability of schools. SCP can help solve problems in schools (Clarke. It can also be used as risk mitigation (Sun et al. , 2. and ultimately can help organizational sustainability planning (Exmeyer et al. , 2. Conclusion From the SEM-PLS analysis in this study, it can be concluded that there is a significant and strong relationship between the influence of SL on OS. HRC on SCP, and SCP on OS. This study examines the direct relationship between the influence of sustainability leadership and SCP on OS and the influence of HRC on SCP at the vice principal work unit level. Further research can examine the same thing from an indirect relationship. It can also expand the geographical area by increasing the number of samples or research on other work units. References
